1. A data storage device, comprising:
a controller, wherein the controller is coupled to a host device, wherein the controller is configured to:
determine a quality of a peripheral component interconnect express (PCIe) link, wherein the quality of the PCIe link is either greater than or less than a threshold quality;
send an alert signal to the host device via a sideband when the quality of the PCIe link is less than the threshold quality; and
transmit an error notification to the host device via the sideband after sending the alert signal, wherein transmitting the error notification comprises transmitting a device status of the data storage device via pulsing a distributed antenna system (DAS) signal in a predefined sequence, and wherein the predefined sequence indicates to the host device a corresponding error code.
